Silly answers. I guess it's a question more than one could use an answer.
Here's my take and my shortcoming. Life needs to be punctuated by events. Day in and day out hum drum all blends into oblivion. The best times and the times that did not fly by are the times I traveled to race. If I did that even twice a year, it was a memorable year.
I think one has to get out on the go and accomplish something while away. I'd say it would be best if it was different than anything related to your work. Hobbies OK.
